If M is the magnetisation induced in the material, H is the magnetic field intensity, B is the net magnetic field inside the material then the correct relation between them is ( ₀= permeability of free space)
Options
- AB= ₀ (H+M)
- BB= ₀(H-M)
- CB= ₀ (H-M)
- DB = ₀( H + M )
Correct answer
D. B = ₀( H + M )
Step-by-step solution
The magnetic field B in a material results from the superposition of the external field contribution ₀ H and the magnetization contribution ₀ M . B = ₀ ( H + M ) For the magnitudes, this simplifies to B = ₀ (H + M) . Among the options, only D) B = ₀ (H + M) matches this relation.
